Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a building remote monitoring system that changes the checking frequency of the device between crime prevention hours and other times.

Traditionally, in small and medium-sized buildings, regular subscriber telephones can be used to report abnormal signals such as failure of equipment in the building, fire outbreak, thieves intrusion, etc. to distant security companies, equipment maintenance companies, and other service companies. This system allows the building manager to be absent and is defenseless against O intrusion, which has a labor-saving effect. We are checking the operation of the telephone line.

However, this system had the inconvenience of increasing the number of calls, increasing telephone charges, and requiring the service company's receiving equipment to be too large.

This invention was made in consideration of the above points, and since the only part that requires operation check at the right angle is the crime prevention system, it operates only during crime prevention hours such as nighttime and holidays when the security system is activated. This method eliminates the inconveniences of the conventional method by performing a check. The present invention will be explained below with reference to the drawings.

FIG. 1 is a diagram showing the configuration of an embodiment of the present invention.
FIG. 2 is a timing chart for explaining the operation of the embodiment shown in FIG.

In FIG. 1, 1 is a flip-flop whose set terminal S is connected to a crime prevention start switch 2, its reset terminal R is connected to a crime prevention end switch 3, and its output terminal Q is one input of an AND gate 4. Connected to the terminal.

The intrusion signal A is applied to the other input terminal of the AND gate 4. 5 is an oscillator of lH7, 6 is a 7200-decimal counter, and 7 is a 600-decimal counter.
output is added, counter 6 operates once every two hours,
Counter T operates J times in 10 minutes. 8 and 9 are one-shot multi-pipe meters, 10.11 is an AND gate, and the inverted output of the flip-flop 1 and the output of the one-shot multi-pipe rake 8 are added to the AND gate 10; The output of the flip-flop 1 and the output of the one-shot multipipe rake 9 are applied to the AND gate 11. 12 is off gate, and Ryokawa Riki of 7nd gate 10.11 is added. 13 is also Oh 7
At the gate, fire occurrence signal a, air conditioning equipment failure signal, power receiving and substation equipment failure signal C1, water supply and drainage equipment failure signal d, lighting equipment fluid failure signal e, engineering V beta failure signal f, 7 Intrusion occurrence signal from gate 4 g, an operation check command signal from the OR gate 12, etc. are added. Reference numeral 14 denotes an automatic dialing device which is activated upon receiving the output from the off-gate 13, automatically dials the service company's telephone number, and when dialing is completed, issues a dial completion signal i. The output of the automatic dialing device 14 passes through an off gate 15 and a disconnector 16, and is sent to a general subscriber telephone line [17]. Reference numeral 18 denotes a telephone set, which is used by switching the disconnector 16 from the illustrated connected state only when in use. 19 is a building number setting switch group, which sets the building management number with a switch; 20 is a building management number data output device, which converts the building management number into a serial signal and outputs it to the general subscriber telephone line 1T; , issues a data output completion signal j. 21 is J! A four-way data output device is connected so that all of the input signals of the off-gate 130 are inputted, converts the input abnormal data into a serial signal, and outputs it to the general subscriber telephone line 17.

Next, the operation of the embodiment shown in FIG. 1 will be explained with reference to the timing chart shown in FIG.

(5) Normally, the output from the oscillator 5 is added to the counter 6, and when the counter 6 counts up 720 (N pulses), an output is output and the one-shot multivibrator 8 is operated.
This produces an output with a pulse width of 20 m5ec. On the other hand, since the output terminal Q of flip-flop 1 is IILI+ and bell, 1. When this is added to one side of AND gate 10, this gate is open, so the above 20
The output of m5ec is O7 game) Automatic dialing is performed from 12.13 to call the service company.

When this is completed, a data output completion signal j is output. Next, the abnormality data output device @21 is activated and outputs an operation check command signal (since no abnormality has occurred yet, the signals a to g indicating abnormality are not output).

The service company receives the data sent and confirms that a signal is coming at a predetermined interval (once every two hours) to determine that it is normal. If the above signal does not arrive within a predetermined time, it is assumed that there is an abnormality, and the service company's staff will be dispatched to the building.

After that, when the security start switch 2 is turned on, the flip-flop 1 is set and the output terminal Q becomes H", so 7
The AND gate 10 is closed and the AND gate 11 is opened in its place. As a result, the inspection interval has been shortened from 2 hours to 10 minutes, and checks will be performed at this interval from now on.

(B) When an abnormality occurs, at least one of the signals a to g becomes "H". In Fig. 2, all the V-pels are set to "H", but in reality, only where there is an abnormality, the level becomes H' (however, the operation check command signal becomes H' at a predetermined time interval). Therefore, as mentioned above, In the same way as above, the building's management number and abnormal data are sent by automatic dialing.

Afterwards, staff will be dispatched to the building to deal with the abnormality.

In this way, when the crime prevention start switch 2 is turned on, the inspection interval becomes 10 minutes, and when the crime prevention end switch 3 is turned on, the inspection interval is reset to 2 hours.

Note that in the above embodiment, the system was pressed to perform a security check only during crime prevention hours, but more specifically, it would be better to check the device at a temperature of 200 degrees during predetermined times such as nighttime and holidays. good. In addition, the degree of thoroughness in checking the operation of buildings with frequent breakdowns may be increased.

Furthermore, in order to reliably detect that security monitoring is being carried out,
A crime prevention start signal and a crime prevention end signal may be sent from the building to the service company. Also, fires and break-ins could be automatically reported to a security company, and equipment failures could be automatically reported to an equipment maintenance company.

Furthermore, the output form of the various data may be any type of encoding, or may be converted into an audio signal and the audio output may be sent to the service company. If equipment malfunctions should be reported to the equipment maintenance company, and if break-ins or fires occur, should be reported to the security company.

The maintenance company rarely checks the operation.
There are many ways to check the operation of the company.

As explained in detail above, this invention allows the device to be checked more frequently during crime prevention hours than at other times, making it possible to perform checks in an extremely rational manner. It has advantages such as being small.
